Claudio Ranieri says he is a long way from retirement despite turning 65 ahead of Leicester's game against Crystal Palace.
Ranieri's birthday did not disrupt his routine on Thursday as he spent the day scouting Saturday's Premier League opponents and fulfilling his media duties.
And the Italian, who has seen his champions prosper in Europe while struggling domestically this season, believes he is good for at least another five years as a manager.
"I'm an old man but I continue," Ranieri said. "I feel good. For me my job is my life, I want to carry on.
"When I started at 35 I said 'okay at 50 I finish'. When I arrived at 50 I said 'why now? 55' Five by five, step by step, 65, 70.
"Life is fantastic, every job is difficult, but it is important to be strong inside because you don't know what happens in life. You can go down but if you are strong you can wake up again.
"When I came to Leicester I came with the priority to build a squad to achieve Europe and then the Champions League - the project of my owner.
"Now we have won but I've forgot, for me we don't win. I continue to build what the chairman asked me the first night."
Leicester made it three wins from three in their debut Champions League season as they beat FC Copenhagen in midweek, and Ranieri expects Palace to pose similar problems at the King Power.
"We made a very good match on Tuesday, but now we think of Crystal Palace," Ranieri added. "They are strong and tall, similar to Copenhagen.
"Palace are strong at the back and then they have good players up front. A good team and well organised. We must be clever.
"I study Crystal Palace from last night, this morning and this afternoon. It's my life, my job and my hobby."
Andy King, Wes Morgan and Jamie Vardy all missed training on Thursday but are expected to be fit as the Foxes aim to improve on a run of eight points from eight league games.
